【Abstract】 The common disinfecting process of drinking water includes free chlorine, chloramine, chlorine dioxide, ozone, UV and membrane etc. The disinfection mechanism, operation characteristic and pathogenetic microorganisms removal efficiency of each disinfection process was discussed. With advanced drinking water treatment technology the disinfecting by products formation potential and pathogenetic microorganisms can be effectively removed. It was recommended that chloramine or chlorine dioxide is used as final disinfectants and ozone oxidation as pretreatment. The application range of UV disinfection technology was also discussed.更多还原
